The Hexoskin biometric shirt is a wearable technology that monitors heart rate (HR), ventilatory rate (VR), minute ventilation (VE), step count, and energy expenditure (EE). It is unknown whether the Hexoskin biometric shirt produces valid results in the field. Participants (N = 26) completed a self-paced 1.6 km trail run wearing the Hexoskin biometric shirt and the COSMED K4 b2 portable metabolic system. Data for HR, VR, and VE were analyzed in six one-minute increments occurring the first three minutes and the last three minutes of the run. Data for step count and energy expenditure were analyzed for the entire trail run. HR, VR, VE, step count, and EE data were analyzed using Pearson product-moment correlation with significance at p < .05. HR, VE, step count, and EE measures at all time points were not significantly correlated. VR measures at all time points were significantly correlated (p < .001). Our results indicate the Hexoskin biometric shirt provides valid measures of VR. For all other measures, the Hexoskin does not provide valid real time results.","PeriodicalId":237335,"journal":{"name":"Sports Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129928054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the 3D trajectory of an object in flight can often be essential in examining variables relating to launch and landing conditions. Many systems exist to track the 3D motion of projectiles but are often constrained by space or the type of object the system can recognize (Qualisys, Göteborg, Sweden; Vicon, Oxford, United Kingdom; OptiTrack, Corvallis, Oregon USA; Motion Analysis, Santa Rosa, California USA; Flight Scope, Orlando, Florida USA). These technologies can also be quite expensive, often costing hundreds of thousand dollars. The system presented in this paper utilizes two high-definition video cameras oriented perpendicular to each other to record the flight of an object. A post-processing technique and subsequent geometrically based algorithm was created to determine 3D position of the object using the two videos. This procedure and methodology was validated using a gold standard motion tracking system resulting in a 4.5 ± 1.8% deviation from the gold standard.","PeriodicalId":237335,"journal":{"name":"Sports Technology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114529726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with electromagnetic tracking systems, it is imperative to determine the reliability of the system with regard to the specific movement of interest to ensure the collection of data that are reliable, interpretable and may be generalized to a broad spectrum of individuals. Thus, the purpose of this study was to establish the reliability of an electromagnetic tracking device (ETD) in analyzing young baseball pitchers. Two data collection sessions in which throwing kinematics were recorded were conducted across a five-day span. Joint kinematics were calculated using the standards and conventions recommended by the International Shoulder Group. Correlation analyses examining inter-day reliability of the ETD showed that the system was within acceptable limits (R > .73). Throughout the selected instances of the pitch cycle, the ETD used in the current study was shown to be reliable across multiple data collection session with ICCs ranging from R = .73 to R = .86. It appears so long as set-up, sensor attachment and digitization protocols remain consistent across data collection sessions, ETD’s are a reliable tool in analyzing throwing movements in younger participants.","PeriodicalId":237335,"journal":{"name":"Sports Technology","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116307865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important trigger for the increasing research attention has been the transition of the sport to a competitive as well as recreational activity and the potential inclusion of sport climbing in the Olympic schedule. The International Rock Climbing Research Association (IRCRA) was formed in 2011 to bring together climbers, coaches and researchers to share knowledge and promote collaboration. This position statement was developed during and after the 2nd IRCRA Congress which was held in Pontresina, in September 2014. The aim of the position statement is to bring greater uniformity to the descriptive and statistical methods used in reporting rock climbing research findings. To date there is a wide variation in the information provided by researchers regarding the climbers’ characteristics and also in the approaches employed to convert from climbing grading scales to a numeric scale suitable for statistical analysis. Our paper presents details of recommended standards of reporting that should be used for reporting climber characteristics and provides a universal scale for the conversion of climbing grades to a number system for statistical analysis.","PeriodicalId":237335,"journal":{"name":"Sports Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134580565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All participants had no prior climbing experience. Results indicated the participants perceived MBVGs and authentic wall/rock climbing were similar concerning climbing tactics/strategies and arm movements, but were different regarding effort and leg, finger/grip, and jumping movements. Moreover, both the MBVGs and “real-life” wall/rock climbing experiences were needed for a significant difference in the participants’ perceived understanding of both the necessary motor skills and tactics/strategies needed to wall/rock climb. In sum, MBVGs may be used as a pedagogical tool to teach strategies of wall/rock climbing, particularly with beginners or those with special needs, but caution must be heeded due to perceived effort and lower extremity movement differences compared to authentic climbing.","PeriodicalId":237335,"journal":{"name":"Sports Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125455398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although bouldering is increasingly popular and competitive, scientific research remains sparse and information on ideal training regimens is limited. The aim of this study was to investigate the effect of interval bouldering on hanging and climbing time to subjective exhaustion. Twenty-four men, highly advanced boulderers (25.2 ± 4.8 years; 1.77 ± 0.07 m; 69.1 ± 5.3 kg; 6.8 ± 3.1 years climbing; 7b Fontainebleau bouldering ability), were randomly allocated to a 4-week interval bouldering (IB with n = 12) and conventional bouldering (CB with n = 12) training regimen. Pre- and posttests consisted of intermittent finger hangs (IFH) and climbing time to exhaustion (CTE). Results indicate significant higher IFH times after 4-week regimen for IB (+27.3 ± 18.4 s, t11 = − 5.16, P < .001), but not for CB (+4.9 ± 11.5 s, t11 = − 1.47, P = .168). Moreover, a significant higher CTE was displayed for IB (+36.2 ± 14.1 s, t11 = − 8.85, P < .001), but not for CB (6.1 ± 19.3 s, t11 = − 1.09, P = .298).

InPutter was designed for research, analysis and training, so as to improve the performance of the golf putting. The device has the same physical properties of a common putter club, thus keeping its ecological validity and being ideal for both novice and expert players. The engineered putter is equipped with an inertial measurement unit, force sensitive resistors and heartbeat radio-frequency receiver compatible with Polar electrocardiogram transmitters. All these are connected to an internal CPU with WiFi technology that allows retrieving all golf putting process variables, in real-time, at a high frequency of 100 Hz. As an internet-connected product, all data can be analyzed on-the-fly using a common interface connected to the cloud (e.g. laptop or smartphone). The putter is battery operated and able to keep an autonomy of up to 4 h, ideal for both Pitch & Putt and traditional Golf games, with a full charge time of approximately 4 h. After describing the hardware and software development, this paper will highlight and assess the benefits of this device by experimentally validating it with a sample of 10 novice golfers.","PeriodicalId":237335,"journal":{"name":"Sports Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114348595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
